From the darkest corners of Equestria a group of Changelings and Griffins, The Shadow Casters, conspired to take over all of Equestria. The first step was to destroy to the Elements of Harmony. To do this they sent fake summons to Princess Celestia, Princess Luna, Princess Twilight Sparkle, Apple Jack, Rarity, Fluttershy, Rainbow Dash, and Pinkie Pie to all meet at the Crystal Castle as soon as every one arrived they attacked all the Crystal Guards were enslaved the mane 6 Princess Celestia, Princess Luna, Princess Candance, and Shining Armor were all that were left to defend the Crystal Castle. After trying the Elements of Harmony and that failing because The Shadow Casters hatred for friendship was so strong that they were able to not be affected by the Elements of Harmony. With the Elements of Harmony nearly out of energy Spike comes out of the library with a book he shows the book to Twilight as she reads it it profices a day when the Elements of Harmony would fail and if that day was to come then that the last of the Magic of Friendship should be used to cast a spell that would summon the only pony that could help them with their situation. The group then decided to give it a try after the spell was cast a blinding flash of white light filled the room and with a deafening crash a brown pony with a black overcoat appeared in front of them his cutie mark is two pistols crossing over a target. Just then a group of ponies that were touring the Crystal Castle came in and saw the situation.
